Solution by Steps
step 1
To find the slope of the tangent line to the curve y=3x22x+1y = 3x^2 - 2x + 1 at x=1x = 1, we first need to find the derivative of the function
step 2
The derivative of y=3x22x+1y = 3x^2 - 2x + 1 is y=ddx(3x22x+1)y' = \frac{d}{dx}(3x^2 - 2x + 1)
step 3
Using the power rule, the derivative is y=6x2y' = 6x - 2
step 4
Now, we evaluate the derivative at x=1x = 1: y(1)=6(1)2=62=4y'(1) = 6(1) - 2 = 6 - 2 = 4
step 5
Therefore, the slope of the tangent line to the curve at x=1x = 1 is 44
Answer
The slope of the tangent line to the curve y=3x22x+1y = 3x^2 - 2x + 1 at x=1x = 1 is 44.
